Application tiled etoloer i., 1915.

To aZZ 'whom t may concern:

Be it known that l, Fnnnrncn MYERS, a citizen of the United States, residing at -New York, in the countyof New York and State of New York, have invented new and useful improvements in Mixers, df which the following is' av specification.

rlhis invention relates to improvements in mixers, and particularly to that class of mixers used in the preparation of beverages composed of several ingredients of 'diilerent speciiic gravity, or condition, as duid or solid, such as milk in a raw, condensed or `dry state, fruit extracts, sugar, mineral or carbonated waters and. the like.

The objects are to provide a mechanism that is especially easy to manipulate, simple in construction and eflicient in operation. -lhese objects are attained bythe novel arrangement and combination ot parte hereinatter described and shown in the accompanying drawings, although. it is to be understood that modifications, variations and adaptations may be made in the structure within the scope of the annexed claims.

Referring to the drawings, Figure l is e side elevation of' an embodiment of thein- .v-ention, illustrating the mechanism inoperative position. Fig. 2 is a plan view of the same, one of the beater spindles being in operative contact and the other held out of engagement. Fig. 3 is a similar `plan view, one oi the spindles .being 'farther removed from. the driving means. Fig. eisen enlarged vertical sectional view through one oi the heater spindles, at the bottom thereo'l, thel spindle being raised. Fig. 5 is a similarl viewfoitthe same, but taken ,attire upper portion, and Fign is a transverse sectional view taken on line 6 6 of Fig. il.

This machine, in contradistinction to prevailing types, rovides for the simultaneous mixing o" two portions or glasses ci the drink at the same operation, thereby saving time and making it possible to lserve 'two persons with freshly m1Xed drinks at the same moment.

The mechanism is mounted von a lease or 'pedestal l0 raised from its supporting suraces by the -feet 1.1,.and having a standard vl2 to which is affixed a bracket il carryingA the electric motor 15, the current carrying Specincation of Letters ateut.

switch handle extending 'forward where it can be conveniently operated.

0n the lower end of the vertical motor shaft is secured a grooved driving wheel 20 having an aendless .circular elastic band tightly engaged in its groove, and acting as adriver for the friction wheels 24C on the These spindles are mounted vertically to rotate in sleeve bearings 26 extendingdown from levers 27 pivl oted by the 4screw stud 28 to the brackets 29, rigidly7 secured to the standardlQ at each side of the motor. Extensions 30 ci' the levers :2? project rearwardly and engageable with them are the levers, pivoted at 33 to the brackets' 29 and. provided with operative handles Si. The levers 27 have oonnecting Abetween them a coiled pull spring 3s secured at its ends to pins 37 such manner .as to draw the spindles normally7 toward each otherand cause the wheels :9A to malte rictional driving `corr-act with the elastic ring 21 v'on the motor shaft. 'The hand levers 34 will then bein the position shown on the left hand side of Figs. 2 and 3,

but when' it is desired to disengage either driver, the springB may be disengaged at one end, allowing thespindles to be swung farther outward. .This is desirable when a new band is to voe placed in position on the driver, or the machine thoroughly cleaned.

The lower portion of the spindle 25 'is preierablyluted or corrugated longitudi nally as shown, and driven'by frictional ccntactjwith the rubber driver l0 attached to the huh 4 1 of the wheels 2.4 as shown in Fig. 4; this driver accomplishes a double purpose, that of transmitting'rnotion and also of clean ing4 the spindle 'in the manner offa scraper or squeegee as the spindle is moved through it by the hand wheel 42, mounted torotate freely at the top of the spindle 25, which at its upper portion is preferably smooth.` By means of the' frictional 'engagement between the spindle' and driver l0 it is pcible to adjust its operative height either when running or still. it the eatremeend of the spindle isl a pair oi beater arms' 45 jformed with the hub 46 adapted to enter a glass or similar container 48, in which. the ingredients of the drink are placed, the arms,l when in operation, thoroughly agitating and miX- ing the contents. These glasses are supported b 7 guides 49 lixed on the upper surface of tlie platform l0 in such manner` that when the spindles are raised, they can be readily removed or replaced.

In operation, one or both glasses being lilled, they are placed in the guides, the spindles lowered by the hand wheels l2 to such depth as may be desired, the hand levers 34 turned forward and the switch 18 depressed thereby starting the motor and causing the beaters to revolve; when the .drink isr mixed as desired, the motor is stopped or the spindles caused to stop rotating by the hand levers and the beaters raised, whereupon the drink is ready tol be dispensed.

Having thus described my invention what I claim as new and desire to obtain by Letters Patent is Y l. In a beater, a pair of spindles having beaters at their lower ends, means for :frietionally rotating either or both of said spindles, means for adjusting said spindles ver tieally, means for maintaining said spindles in an adjusted position and means for moving said spindles laterally with respect to the driving means.

2. In a beater, the combination with a base, a stand rising therefrom and a motor vertical on said stand, oi' a. pair of spindles having beaters at their lower ends, Wheels on said spindles adapted to be rictionally driven by said motor, means for keeping said wheels normally in engagement with said motor, and levers for disengaging said wheels therefronfr.c

3. ln a. beater, the combination with a base, a stand rising therefrom and a motor vertical on said stand, of a pair of spindles having beaters at their lower ends, wheels on said spindles adapted to be frictionally driven by said motor, means combined with said wheels for transmitting rotary motion to said spindles, said means also aotingas Wipers therefor, and means for raising or lowering said spindles independently of said wheels.

4. In a. beater, the combination with a base, a stand rising therefrom and a motor vertical onsaid stand, of a pair of spindles having beaters at their lower ends, wheels on said spindles adapted to be frictionally driven by said motor, levers for actuating said wheels into and out of engagement with. said motor, a removable tension means be tween said spindles, means for holding said spindles at any desired height when rotating or quiescent, and a manually operated means for raising or lowering said spindles, said means being non-rotatable while in thegrasp of the operator. l

5. ln a beater, a pair of spindles having beaters at their lower ends, means for fricn tionallyrotating either or both of said spin dles, levers upon which .said spindlesy are mounted, means for constraining said levers normally toward each other, means whereby said constraining means may be released, means for operating said levers whereby said spindles may be positively moved to or from the driving means, means for raising and lowering said spindles and means for wiping said spindles as the are raised.

ln testimony whereof ave signed my name to this specification.
